Benefits of technology

[0006]The present invention relates to a decision support system, which enables the clinician to get an overview of physiological parameters of a patient in relation to current and future ventilator settings by presenting scoring values calculated/determined from physiological parameters, respirator settings and clinical preferences. The scoring values are displayed for different pairs of scoring values of the patients, which have conflicting effects in response to over-ventilation and under-ventilation in a graphical user interface (GUI). An example is lung trauma vs. acidosis, where acidosis may be compensated for by increasing ventilation pressure. On the other hand increased ventilation pressure may result in lung trauma. To complicate the case further, the different physiological parameters have different scales and units, and a change in the different physiological parameters (e.g. in response to changed ventilator settings) therefore reach critical levels on different scales.

Problems solved by technology

On the other hand increased ventilation pressure may result in lung trauma.
Overall, these differences make it difficult for the clinician to maintain an overview for all parameters, their relation to clinical preferences and the balancing of these against each other simply by looking at measured numbers for each parameter.

Embodiment Construction

[0103]As described above, the core aspect of the invention is the use of preference functions to calculate scoring values and corresponding preference zones / areas 15 from clinically measured variables allowing integration of relevant mechanical ventilation variables for a patient into a single presentation covering the contrasting preferences related to mechanical ventilation helping the clinician to minimise risk of over-ventilating and under-ventilating the patient.

[0104]FIG. 1 is a schematic drawing of a mechanical ventilation system 10 for respiration aid of an associated patient 5, P, the system being adapted for displaying / plotting information of physiological parameters in a manner providing the clinician with information which is difficult to subtract from mere number values. The respiration aid may be fully controlled or supported.

[0105]The system comprises ventilator means 11, VENT capable of mechanical ventilating said patient with air and / or one or more medical gases, e....

Abstract

The present invention relates to a ventilator system capable of displaying complex information patterns in a GUI, thereby allowing a clinician to get subtract complex information from multiple parameters inputs.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to a decision support system for lung ventilator settings. In particular, the present invention relates to a decision support system for lung ventilator settings, which displays technical features of measured physiological parameters providing the clinician with decision support in relation to ventilator settings.BACKGROUND OF THE INVENTION[0002]Patients residing at the intensive care unit typically receive mechanical support for their ventilation. Selecting the appropriate level of mechanical ventilation is not trivial, and it has been shown that appropriate settings can reduce mortality [1].[0003]A challenge with the settings of a mechanical ventilator is that each setting may be beneficial for one physiological parameter of the patient but negative for another physiological parameter. Currently the clinician may get help by ventilator screens, extra devices monitoring physiological parameters (capnograph, pulseox...
